  • Ask Hackaday: Whatever Happened To Wire Wrapping? | Hackaday
    #diy | Such connections are gas-tight, so oxygen is excluded from the mating surfaces and oxidation inside the joint is avoided. This also lets the wire and post form a cold weld, significantly reducing the resistance of the connection.

  • Wire Wrap Is alive And Well! | Nuts & Volts Magazine
    #diy | It's relatively fast, reliable, simple, solderless, inexpensive, and easy to learn. Wire wrap has been successfully used for decades by the telecom/datacom and controls industries. It is ideal for complex one-of-a-kind circuits and systems.

    This absurdly entertaining method of building electrical circuits looks so crazy that I was stoked to discover that it is actually quite robust. I mean it went into space! SPACE!

  • The Ultimate Spherical Speakers Made from 4 Sets of IKEA Bowls
    #diy | Many DIYers have built “full range” speakers using a single sphere from IKEA bowls. I set out to build a true full frequency spectrum 4-way speaker from IKEA bowls, using all three sizes, 5”, 8” and 11”.

    and they look amazing!

  • Electronic project kits: hands on with a vintage 160-in-1
    #diy #electronics #retro | With a modest number of components, 160 projects could easily be built by inserting wires into the spring terminals connected to each component. An included manual guided you through each of the projects, introducing new concepts and providing structure, while still offering some latitude of freedom to tinker...

    This hardware set is a real gem that deserves to be preserved and described. I wish I could find something like this for my kid... There's so much immediacy about it, no mobile app interfering with your experience, just the kit, the manual book and you.
